garyneedsz Posted June 22, 2009 Share Posted June 22, 2009 ok so i bought this junked block that has been sitting for a couple of years. the po said that it ran fine when before he pulled it, no leaks or anything of that matter. i did the usual, machined the head, new gaskets and such. the car is on two stands. when i was underneath my 280, i noticed that there was coolant leaking. it was a stream of coolant running along from the front of the oil pan, to the back. one other fact. on the l6 motors, there are two nipple like thingies that pop out from the block so the head could match up to it perfectly. i forgot to put those on. so i was wonering if those two nipple things could be the problem. thanks.

Xnke Posted June 24, 2009 Share Posted June 24, 2009 Yes, not having the alignment dowels is a problem. You will want to fix that, methinks. Quote Link to comment Share on other sites More sharing options...
woldson Posted June 24, 2009 Share Posted June 24, 2009 from the front of the oil pan Where is it coming from before it hit the oil pan? Quote Link to comment Share on other sites More sharing options...
garyneedsz Posted June 24, 2009 Author Share Posted June 24, 2009 msa thought i was retarded. i was like. im looking for these two parts that go between the head n the block. there all, uhh. a headgasket?? anyways. yes i dont hve those "dowels" in, and i have discovered a leak between the head n block near cylinder one on the passenger side. i dropped the oil pan a few days ago. there seems to be another leak coming from inside of the timing cover. its dripping also from the passenger side near the bottom. do you think its the same leak? or different, cause there both at cylinder one.

thrustnut Posted June 25, 2009 Share Posted June 25, 2009 I agree with the dowels.. they should be in. Have you checked to make sure you dont have a leak from your thermostat housing where it bolts to the head? I think there and the head gasket are your only options.
